Integer BASIC - Switching Between BASICs

Switching Between BASICs

When running Apple DOS, it was possible (at the expense of clearing the current BASIC program from memory) to switch between Applesoft BASIC and Integer BASIC by typing either INT (to enter Integer BASIC) or FP (to enter Applesoft BASIC)—provided, of course, that the requested language was either in ROM or loaded into RAM.

There was also a plug in board available that could be installed into slot 0 that allowed the user to switch between the on board or external ROMS.

The command-line prompt for Integer BASIC was a right-facing arrowhead (greater-than symbol) (>). (Applesoft's prompt was a right square bracket (]), giving the user a clear indication which BASIC they were using.)
